Description
Technical field
It is more particularly to a kind of to be used for test material mechanical property parameters the present invention relates to material mechanical performance test equipment
Survey tool.
Background technology
Various parts are bonded usually using double faced adhesive tape in intelligent terminal, for example, touch-screen is bonded by foam double-faced adhesive
On housing, battery is by easy-to-draw glue sticking on housing, and it is first-class in housing that camera eyeglass passes through common two-sided glue sticking.For
Part is avoided the occurrence of with the situation of housing disengaging, it is necessary to the tensile strength of testing two-sided glue.
Existing method of testing by double faced adhesive tape 12 between two test suites 13 as shown in figure 1, be bonded, two test suites
13 one end is respectively sleeved on two circular iron props 11, when two circular iron props 11 are moved in the opposite direction, can produce drawing
Power F, stretches separation, so that the tensile strength of testing two-sided glue by the test suite 13 of two stickups.But, because the side of pulling force
Perpendicular angle to the direction with double faced adhesive tape, by this way can only testing two-sided glue tensile strength, it is impossible in pulling force
The direction of direction and double faced adhesive tape there is the mechanical property of testing two-sided glue in the case of angle.
In addition, there is many fragile materials in intelligent terminal, most of is core devices.So-called fragile material, is exactly outside
The deformation material that i.e. destruction is broken even generation very little (is such as stretched, impacted) under power effect, for example, handset touch panel, LCM
Glass, fingerprint key panel, camera eyeglass etc., fragile material is in use because stress or material have initial lacking in itself
Fall into, can produce initial crack and constantly extend causes failure.To avoid fragile material in use from failing, it is also desirable to test
The crack propagation process of fragile material multi-angle.
But, conventionally, as the crack propagation velocity of fragile material is general quickly, traditional method of testing without
Method effectively observes direction and the speed of Crack Extension, and, the test of the crack propagation process of fragile material multi-angle with it is two-sided
The test of the mechanical property of glue is separated and independently performed, and not enough facilitates.
The content of the invention
The test with the mechanical property of double faced adhesive tape is tested for the crack propagation process for solving above-mentioned fragile material multi-angle
It is the problem being separated and independently performed, the embodiment of the present invention proposes a kind of measurement work for test material mechanical property parameters
Tool.
